【摘要】 以一种双向拉伸聚丙烯（ＢＯＰＰ）薄膜在不同温度下进行恒温处理，然后进行负电晕驻极。结果表明，ＢＯＰＰ薄膜随恒温处理的温度升高，热刺激电流（ＴＳＣ）峰值愈低。利用经验方法，估算了它们的活化能，并探讨了导致ＴＳＣ峰温变化的原因。更多还原

【Abstract】 In this paper,it was discussed that the properties of the biaxial stretching polypropylene which received the treatment of negative-corona charge after being treated under different temperatures. The results shows that the peak temperature of thermally stimulated discharge currant of BOPP decreased with the increase of treatment temperature.With experimential method the activation energy of BOPP film was reckoned and the cause of the change of its TSDC peak temperature.更多还原
